1. Photovoltaic modules are the only source of power generation The module converts the energy radiated by sunlight into measurable DC electric energy through the Photovoltaic effect, and then has the subsequent conversion output, and finally obtains the power generation and income. Without components or insufficient component capacity, even the best inverter can do nothing, because the solar inverter cannot convert air into electrical energy. Therefore, choosing suitable and high-quality component products is the best gift to the power station; it is also an effective guarantee for long-term stable income. The design is very important. If the same number of components adopts different stringing methods, the performance of the power station will be different.
2. The laying and installation of components is crucial The same solar module capacity in the same installation site, the orientation, arrangement, inclination of the solar module installation, and whether there is obstruction, all have an important impact on the electricity. The general trend is to install facing south. In actual construction, even if the original state of the roof is not facing south, many users will adjust the bracket to make the module facing south as a whole, in order to receive more light throughout the year radiation.
3. Grid fluctuation factors must not be ignored What is “grid fluctuation”? That is, the voltage value or frequency value of the power grid changes too much and too frequently, which causes the load power supply in the station area to be unstable. Generally, a substation (substation) has to supply power loads in many areas, and some terminal loads are even dozens of kilometers away. There are losses in the transmission line. Therefore, the voltage near the substation will be adjusted to a higher level. The photovoltaics connected to the grid in these areas The system may have a standby situation because the output side voltage is raised too high; or the remotely integrated photovoltaic system may stop working due to a system failure due to a low voltage. The power generation of the solar system is a cumulative value. As long as the power generation is in standby or shutdown, the power generation cannot be accumulated, and the result is that the power generation is reduced.
During the automatic operation of the Blue Joy solar system, even it is on grid or off grid solar power station with lithium ion battery back power, it is necessary to arrange regular inspections, operation and maintenance, to grasp the dynamics of all aspects of the power station in real time, to eliminate the unfavorable factors that may affect the power station’s mean time between failures in time, and to ensure the stable output of the power station.
